Since November, there have been more than 20 earthquakes in, or near, the city of Azle. The most recently quake, the 24th for the area, occurred on Jan. 13. (Click here to see a Google map pinpointing all Northern Texas earthquakes recorded by the USGS since Nov., 2013.)

Many people in the area have reported property damage, including cracked walls and sinkholes.

In early January, representatives from the Texas Railroad Commission, the group that regulates drilling, attended a meeting in Azle to discuss the earthquakes. More than 800 people showed up, many of whom upset that the panel didn’t take questions.
